Today, I almost pulled in 5K in Mersenne. That's with two dual cores running at 3 Ghz and 64 bit Linux.

We're almost a half way to 1M as a team. The way credits seem to be coming out now, it may be a good time to push for the team million-stone.

Do they report both claimed and granted credit? If so, what is the ratio of granted/claimed?

Granted is 68.34 per.

It takes one of my cores a little under 1.5 hours to complete one.

Good to know. I may have to check that out again soon. Thanks!

Seems to like AMD a lot more than intel. My Core2 machines are getting only ~20 c/h.

That's the kind of info that would be good on a "project strategy" sticky inside the new team only forum there.
If we compile enough data on when and how to crunch each project, as a team, we would be light years ahead of the "Average Joe" in efficiency. :cool:

It looks like more of a case of it liking Linux more than Windows. Of course the project admin crunches with Gentoo. His completion times match mine pretty well.

(I think this is one that Mr. Hankey should probably jump on for a while)

Well, after further investigation, yes, AMD definitely has an advantage.

Which is the greater advantage? Linux over Windows or AMD over Intel?

My AMD box runs WinXP x64. Is it worth the effort?

Run 10 tasks, figure out the c/h average, and let us know what you learn!

The people who are doing best by far are the ones using 64-bit Linux on AMD.

Let's get some data and find out!

Well, here's a little experiment in progress:

Dual AMD Opteron 2.6 Ghz Dual-Core (http://mersenneathome.net/results.php?hostid=1699&offset=0&show_names=0&state=3)

So, 48.58 and 51.72 Credit/Core/Hour so far.

NOTE: And that's an Ubuntu 10.10, 64bit machine.

EDIT2: After 26 tasks, the average is currently 46.89345536 C/C/H which is about 4.5K daily for this machine. This machine had been getting 1.5K daily on Spinhenge.

For comparison, both my machines are 3 Ghz Intel dual core running Gentoo 64. Over 20 tasks they average 46.9 Credits/Core/Hour

What do you think i'm doing over here :)

I just ran several tasks with ubuntu 64 in a VM on my Mac Pro. It paid 52 c/h. I am installing a ubuntu 64 VM on a win box now, just to double check. Both machines are Intel Core2 Xeon X53xx machines.

But yeah, it looks like linux is the primary factor in getting ~3x the c/h. At least comparing win64 vs lin64. Not sure what a 32 bit version of either OS would do.

If no one else gets to testing an AMD box running XP x64 by this weekend I'll give it a look see. I will also test Ubuntu x64 on that box using my pen drive w/persistence. I have other team stuff that I've fallen behind on.......

Update after I have 5-6 results from both machines. The two VMs are identical (ubuntu 64).

OSX 10.6.6 w/ dual X5365 (3.0 ghz): 52 c/h

XP64 w/ dual X5355 (2.66 ghz): 40 c/h

Not sure if the difference is purely due to CPU speed. That doesn't seem likely to account for such a large difference. Perhaps the underlying OS of OSX is more efficient in some way.
